WINDLASS.

SPECIFICATION forming part of Letters Patent No. 292,376, dated January 22, 1884.

Application filed June 26, 1883. (X0 model.)

To all whom it may concern.-

Be itknown that I, WILLIAM: SMITH, a citiin the county of Monroe and State of Wisconsin, have invented certain new and useful Improvements in WVindlasses, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain improvements in windlasses; and it has for its objects to provide a Windlass that may be conveniently transported from place to place, that will be cheap and durable, and that will exert great power, and is specially designed for purposes where a portable Windlass is required. These objects I attain by the means illustrated in the accompanying drawings, in which Figure 1 represents a perspective view of my improved Windlass; Fig. 2, a vertical sectional view of the same, and Fig. 3 a side elevation of my improved slack pulley used in connection with my improved device.

In the drawings, the letter A indicates the frame of the Windlass, which is constructed, preferably, of wrought-iron, which is angular at one side, and on top, at right angle to the angular portion of the frame, extends an arm, B. Between said arm and a suitable brace, O, is mounted a roller, D, which serves to keep the draft-rope E in place.

The letter F indicates the drum of the machine, having an upward extension projecting through the main frame, and from the short upward extension extends an outwardly-extending lever, G, which is notched on its outer end, as indicated by the letter H, as will hereinafter be described. This outwardly-extendcan be made separately, butmust be fastened securely to the drum, so that it will turn with it.

Passing through the drum F, and holding it to the base of the indlass, is a long bolt, I,

ception of thelong lever L, by which the windlass is operated. The lower end of this bolt I is secured in any suitable manner, so that the bolt will turn freely through the drum when necessary. On the levers slips a loose link or strap, M, which, when it is necessary to operate the drum, is passed over the short leverG and into the notch H, thereby holding the long lever securely to the short lever, so that when the long lever is operated it will carry the drum around withit. The frame, which rests upon and is attached to the base, has its angular end secured to a stake or any rigid support, N, by any manner or means. The rope E extends around the pulley O, which is located in a sheave, P, which has connected to it a rope or chain, Q, which passes around a pulley, It. This pulley Bis notched on its periphery, as indicated in the drawings, and has passing through it a short shaft, or fastened to its sides lugs or projections, S, on which it turns. These lugs or projections or short shaft has bearings in slots T on both sides of the pulley, said slots being formed in a slotted arm, U. one end of which is formed in the shape of a hook, and the other end being formed of such shape as will fit exactly in the notches in the periphery of the pulley, for the purpose hereinafter described.

The operation of my invention is as follows: The windlass being placed in position, and being securely held by means of a chain or otherwise to a rigid support, the rope E passing around the pulley O, as described, and the rope Qibein'g fastened to the sheave thereof and passing around the pulley R, as shown, the hook is hooked by any means to the object to be moved. Should the rope be too long to start with, instead of operating the lever to draw it taut, you simply pull the rope Q through the pulley until itis tight; then, when you operate the lever, the strain being so great, the pulley, sliding in the slotted arm, (which arm is secured at one end by means of the hook to the object to be moved,) has a tendency to pull and cause the other end to bite the rope and pulley, keeping the pulley-from turning, and by so doing making a fast connection. 7

As will be plainly seen, when the rope is all wound on the drum, instead of operating 'the lever in the opposite direction to unwind it, you simply remove the strap or link which connects it to the short lever of the drum, and attaching any power to the end of the rope, the drum will turn or unwind without disturbing the position of the lever.

Having thus fully described my invention,

what I claim; and desire to secure by Letters Patent, is-

1. The combination, in awindlass, of the frame and its base, a drum having an upward a slack pulley, substantially as and for the and outward extension, a bolt which turns and purposes set forth. :0 passes through said drum, having an eye in I In testimony whereof I affix. my signature in which fits the end of the operating-lever, and a presence of two witnesses.

\ link or strap that slides on the lever, as and \VILLIAM SMITH.

for the purposes herein set forth. Vitnesses;

2. In combination with the Windlass, as I-IATTIEAUBERY, constructed and described, and attachments, I
